## Custom menu builder for Sup Game Box 400-in-1. Requires actual ROM image!

To successfully build the menu, you need to get some knowledge on how the unit works etc: [article](https://nyh-workshop.github.io/Custom-ROM-Sup-Game-Box-400in1/).

![image](https://github.com/user-attachments/assets/38b81606-8157-4644-a5c4-743f39a1f476)

You also need these:

- [CC65](https://cc65.github.io/) installed and path set.

- Getting this [template menu](https://github.com/nyh-workshop/CustomMenu_Sup400in1).

- The [OneBusCalc](https://github.com/nyh-workshop/OneBusCalc) to calculate the OneBus registers for the system to jump to the appropriate address.

- and finally, this app.

Directions:

- Run this menu builder app. Supply the template menu folder link into the "Build Folder".

- Add NES games (**only Mapper 0 and MMC3 games supported now!**) inside by pressing **Add Item**. You can move items up and down in the list!

- With your OneBusCalc, determine the start PRG and CHR addresses. Make sure it is from **0x90000 onwards** because 0x80000-0x8FFFF is the custom menu code!

- Also, with the OneBusCalc, adjust the values of these "PRG and CHR Registers" accordingly. Once you are satisfied with it, click on "Generate Code".

- From the OneBusCalc, after "Generate Code", copy and paste the bottom output **without the square brackets** into the Menu Builder's "Config OneBus" entry box.

- Finally, press "Compile". When it is successful, go to the cmd and run "make". The make will compile the menu, and combine the apps into the main binary.

- Run this output_final.bin with an emulator such as EmuVT 1.36.

- You can save the games list into the **CSV file**, or you can load them too!
